*disclaimer* as I have said many times before, I do not own any of Tolkien's characters, as he is the one who created them.
Prologue
Although it has been said that Elves, being immortal, did not know of sickness or pestilence, Gilauriel proved it wrong. At a young age, she became deathly ill. The Elves did no know what it was, so they could do nothing but pray and hope that the young Elf would survive.
Gilauriel lived in Rivendell at the time and even Lord Elrond, a close friend of her father Eluan, did not have the medicine or power to penetrate the sickness. A fever struck her, and she was delirious for many days. During that time her mother Gilaeren and her brothers stayed at her side, never stopping to worry for her.
The fever broke soon after, but it left Gilauriel blind forever. Her parents became afraid that they would no longer be able to raise their youngest child, so they left her in the care of Elrond. Upon the departure of her brothers destined to guard the precious Wood Lothlórien, her mother and father requested that Elrond would never speak of her brothers or her parents to ease the pain of their passing. She would set out in search of them if she learned of them.
The next day, Eluan and Gilaeren began their journey West to sail to the Undying Lands.
Time progressed, and Gilauriel became accustomed to her new surroundings, memorizing exactly where an area in Rivendell would be. Arwen, the daughter of Elrond grew to be her friend, guiding her around in new places. Elrohir and Elladan, Arwen's twin brothers, also were kind to her because of her disability.
Blind though she was, Gilauriel's ocean-green eyes remained unfailingly clear. Many mistook her as being able to see, and sometimes, to bother her, Elrohir would wave a hand in front of her to check if her sight had miraculously returned.
And Elrond, seeing that Gilauriel had matured and grown in her years, knew that the time had come for her to know of the secrets hidden from her.
